AISI 1015 Steel, cold drawn Product Information -:- For detailed product information, please contact sales. -: ## **Product Specification: AISI 1015 Low Carbon Steel, Cold-Drawn** ### **Product Designation** * **Standard Name:** AISI 1015 / SAE 1015 * **UNS Number:** G10150 * **Condition:** **Cold-Drawn** * **Common Forms:** **Round, Hexagonal, Square, Flat Bar; Wire** * **Key Features:** Excellent combination of strength, ductility, and **superior machinability**; bright smooth surface; precise dimensional tolerances; good case hardenability. ### **Overview** AISI 1015 cold-drawn steel is a premium, ready-to-machine form of one of the most versatile and widely used low-carbon steels. The cold-drawing process imparts significant improvements: a smooth, scale-free surface, excellent dimensional accuracy, and enhanced yield and tensile strength through strain hardening. With a carbon content that optimizes both **machinability and case hardenability**, AISI 1015 cold-drawn is a first-choice material for a vast range of precision components that may undergo machining, carburizing, or both. It strikes an ideal balance between performance and manufacturability, making it a cornerstone of high-volume component production. --- ### **1. Chemical Composition (Typical % by Weight, AISI/SAE Standard)** The composition is carefully balanced for versatile manufacturing. | Element | Content (%) | Role & Effect | | :--- | :--- | :--- | | **Carbon (C)** | 0.13 - 0.18 | **Optimal balance element.** Provides good base strength, excellent machinability (prevents gumminess), and is the perfect level for effective **case hardening (carburizing)**. | | **Manganese (Mn)** | 0.30 - 0.60 | Enhances strength and hardenability. Critical for achieving a good case depth during carburizing. | | **Phosphorus (P)** | 0.040 max | Impurity; controlled. | | **Sulfur (S)** | 0.050 max | Impurity; often maintained to aid machinability, though not as high as in free-machining grades. | | **Iron (Fe)** | Balance | Primary constituent. | --- ### **2. Physical & Mechanical Properties (Cold-Drawn Condition)** **A. Physical Properties** * **Density:** 7.87 g/cm³ (0.284 lb/in³) * **Elastic Modulus (E):** 200 GPa (29,000 ksi) * **Poisson's Ratio:** 0.29 * **Thermal Conductivity:** ~59.5 W/m·K * **Electrical Resistivity:** ~11.7 μΩ·cm **B. Mechanical Properties (Typical for Cold-Drawn Bar)** *Properties are anisotropic due to cold work.* * **Yield Strength (0.2% Offset):** **450 - 690 MPa (65 - 100 ksi)** *[Substantially higher than hot-rolled]* * **Tensile Strength:** **560 - 790 MPa (81 - 115 ksi)** * **Elongation in 50 mm:** **7% - 15%** (Adequate for handling). * **Hardness (Brinell):** **170 - 235 HB** * **Surface Finish:** Smooth, bright, and scale-free. Excellent for plating, painting, or direct assembly. * **Dimensional Tolerance:** Meets precise **ASTM A29** cold-drawn tolerances. * **Machinability:** **Excellent.** A benchmark material for machining. Superior chip control and surface finish compared to lower carbon steels. * **Hardenability:** **Low (through-hardening), Excellent (case hardening).** Cannot be through-hardened but is **one of the most popular steels for carburizing**. After carburizing, surface hardness can reach 60-65 HRC with a tough, ductile core. * **Weldability:** **Excellent.** No pre-heat required, but welding anneals the cold-worked HAZ. --- ### **3. Product Applications** AISI 1015 cold-drawn is a fundamental material for manufactured parts across industries, especially where surface hardening is planned. * **Case Hardened Components (Primary Application):** * Gears, pinions, camshafts, bushings, bearing races, and chain pins that are carburized after machining. * **Precision Machined Parts:** * A staple for screw machine products: fittings, connectors, spacers, sleeves, and fasteners. * **Shafts & Pins:** * Dowel pins, hinge pins, guide rods, and light-duty shafts, often surface hardened for wear resistance. * **Fastener Stock:** * High-quality material for cold-headed bolts, studs, and screws. * **Automotive Components:** * Transmission parts, linkage components, steering system pins, and various carburized wear parts. * **General Machinery:** * Any component requiring a combination of machinability, good strength, and the potential for a hardened surface. --- ### **4. International Standards & Designations** | Standard System | Designation | Notes / Key Comparison | | :--- | :--- | :--- | | **SAE / AISI (USA)** | **SAE 1015 / AISI 1015** | Standard designation. | | **UNS (USA)** | **G10150** | Unified Numbering System. | | **ASTM (USA)** | **ASTM A108** | Governing specification for cold-finished bars. | | **DIN / EN (Germany/EU)** | **C15E (1.1141), C15D (1.1141)** | **C15E** (engineering steel) and **C15D** (bright steel) are direct equivalents. The sheet equivalent is **DC01/DC03 (EN 10130)**. | | **JIS (Japan)** | **S15C (JIS G4051), SWRCH15A (JIS G3507)** | **S15C** for steel bars; **SWRCH15A** for cold heading wire. | | **GB (China)** | **15, ML15** | **15** is the standard grade; **ML15** is for cold heading. | | **ISO** | **ISO 683-18: G15** | For bright steel products. | --- ### **Processing & Design Considerations** 1. **Case Hardening Champion:** The carbon content is ideal for absorbing carbon during carburizing, creating a deep, hard case while the lean core remains tough. This is its most significant advantage over 1010/1012. 2. **Machining Performance:** Offers excellent machinability, making it cost-effective to produce complex pre-hardening geometries. 3. **Stress Relieving:** Recommended before or after severe secondary forming to reduce springback. 4. **Anisotropy:** Account for lower transverse ductility in design. 5. **Versatility:** Uniquely suited for a two-step process: **1) Easy machining in the soft state, 2) High surface hardening** for wear resistance. ### **Summary** **Cold-drawn AISI 1015 is the quintessential dual-purpose low-carbon steel, expertly engineered for both superior machinability and exceptional case hardenability.** It is the industry standard for components that require a precision-machined form followed by a wear-resistant hardened surface. This combination of easy fabrication and high-performance potential makes it indispensable for gears, shafts, and countless mechanical parts. Governed by **ASTM A108** and recognized globally as **JIS S15C** or **DIN C15E**, it is a universally specified, reliable, and cost-optimized material that bridges the gap between soft, formable steels and high-alloy grades. -:- For detailed product information, please contact sales. -: AISI 1015 Steel, cold drawn Specification Dimensions Size： Diameter 20-1000 mm Length <4751 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: AISI 1015 Steel, cold drawn Properties -:- For detailed product information, please contact sales. -:
